Pollution, Storms And Climate: NASA Mission Investigates How They Interact
2013-06-07 11:09:55

April Flowers for redOrbit.com - Your Universe Online To investigate how air pollution and natural emissions, which are pushed high into the atmosphere by large storms, affect atmospheric composition and climate, NASA´s DC-8 and ER-2 science aircraft will take flight over the southern US this summer. This will be the most complex NASA airborne science campaign of the year drawing together coordinated observations from NASA satellites, aircraft and an array of ground sites. The...

Strength In Developing Atlantic Tropical Low Seen By NASA Satellite
2012-08-02 07:41:19

NASA's Aqua satellite spotted some very cold, high, thunderstorms around the center of a tropical low pressure area in the Atlantic Ocean today, indicating that the system is getting stronger and more organized. The low pressure area, designated as "System 99L" was located about 850 miles east of the southern Windward Islands, near 10.7 North latitude and 46.9 West longitude. It was moving west between 15 and 20 mph. NASA's Aqua satellite passed over System 99L on August 1 at 0405 UTC...

Satellites have been busy this week covering severe weather across the U.S. Today, the GOES-13 satellite and NASA's Aqua satellite captured an image of the huge stretch of clouds associated with a huge and soggy cold front as it continues its slow march eastward. Earlier this week, NASA's Tropical Rainfall Measuring Mission satellite captured images of severe weather that generated tornadoes over Louisiana. Today the eastern third of the U.S. is being buffered by a large storm that stretches...

Tropical Storm Alex, the first storm of the 2010 Atlantic hurricane season, continues to pick up steam as it crosses the western Gulf of Mexico. According to NOAA's National Hurricane Center, Alex is expected to approach the coast of northeast Mexico and southern Texas on Wed., June 30, and make landfall Wednesday night. The storm is expected to reach a peak intensity of 80 to 85 knots (92 to 98 miles per hour) before landfall, which would make it either a strong Category One or weak Category...

Researchers studying climate now have a new tool at their disposal: daily global measurements of carbon dioxide and water vapor in a key part of Earth's atmosphere. The data are courtesy of the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft and confirm the mainstream scientific view that large changes in the climate are likely over the next century. Moustafa Chahine, the instrument's science team leader at NASA's Jet Propulsion Laboratory in Pasadena, unveiled the...

U.S.-led scientists say the solar cycle, Earth's stratosphere and oceans work in sync to produce global weather patterns. The researchers, headed by the U.S. National Center for Atmospheric Research, said their findings will help in predicting the intensity of certain climate phenomena, such as the Indian monsoon and tropical Pacific rainfall, years in advance. An international team led by the National Center for Atmospheric Research in Boulder, Colo., used more than a century of weather...

Researchers from NCAR have created the first-ever model to simulate the impact of the sun's radiation fluctuations on the earth's climate. Scientists have long known that the sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. But experts have previously been unable to create a model that would depict how uneven radiation would impact the earth's climate. "Small changes in the sun's output over the 11-year solar cycle have...

Determined to understand why some storms grow into hurricanes while others fizzle, NASA scientists recently looked deep into thunderstorms off the African coast using satellites and airplanes. During July and August 2006, a team of international scientists, including NASA researchers, journeyed to the west coast of Africa. Their mission was to better understand why some clusters of thunderstorms that drift off the African coast, known as easterly waves, develop into furious hurricanes, while...

U.S. scientists say they've determined rain evaporation and continental convection play an important part in the tropical water cycle. The researchers, led by John Worden at the National Aeronautics and Space Administration's Jet Propulsion Laboratory, analyzed global measurements of the isotopic composition of water vapor from NASA's Tropospheric Emission Spectrometer to determine the processes driving the tropical hydrological cycle. The scientists say they discovered rainfall...

NASA -- Hurricanes can completely re-structure themselves inside, and that presents forecasters with great uncertainty when predicting their effects on the general population. Recently, scientists used data from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite to analyze transformations that take place inside a hurricane. Stephen Guimond, a graduate research assistant at Florida State University, Tallahassee, Fla., lead a study that used TRMM data to view the height at which ice...
